   |               MISCELLANEOUS TECHNICAL NOTES                |
   |------------------------------------------------------------|
   |   BT-757D is a differential SCSI controller. Terminators   |
   |     RP2, 4, 6, 8, 10, and 12 contain 150ohm resistors.     |
   |    Terminators RP3, 5, 7, 9, 11, and 13 contain 330ohm     |
   |                         resistors.                         |
   |                                                            |
   | BT-757S is shipped with three resistor packs on-board, at  |
   |  the same locations as RP6, 7, and 13. Each pack contains  |
   |                     110ohm resistors.                      |
